A standard cholesterol panel reports four things: total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides. "Advanced" heart labs add markers the standard panel cannot show. The three with the clearest place in guidelines are ApoB, Lp(a) and hs-CRP.
The standard panel is not obsolete. It is still the starting point for every risk calculator. The added tests matter most when your risk is uncertain, when heart disease runs in your family, or when your cholesterol looks fine and something still does not add up.
Key takeaways
- A routine panel measures cholesterol amounts, not the number of particles, inherited Lp(a) or inflammation.
- Lp(a) is the one added test that US guidance now advises for every adult, a single time.
- ApoB and hs-CRP are optional extras in guidelines, used to refine an uncertain risk estimate.
- For predicting risk across a whole population, the basic panel already does most of the work.
- Both Cardio Res-Q assessments include ApoB, Lp(a) and hs-CRP.
What a standard panel tells you
The routine panel is cheap, widely available and well studied. Total and HDL cholesterol feed the risk calculators that guidelines use, and LDL cholesterol is the number most treatment goals are written around.
It is also stronger than its reputation in some marketing. In a UK Biobank analysis of 346,686 adults, total and HDL cholesterol captured the cholesterol-related risk of heart and stroke events, and adding apolipoprotein tests gave no meaningful improvement in prediction.1 That finding is about populations. It does not mean the extra tests never change the picture for one person.
Standard and advanced labs compared
| Test | What it adds | What guidelines say |
|---|---|---|
| Standard lipid panel | Total, LDL and HDL cholesterol, and triglycerides | The basis of risk assessment for all adults |
| ApoB | A count of all plaque-forming particles | Optional. A high result is a risk-enhancing factor |
| Lp(a) | An inherited particle the standard panel cannot separate out | Measure once in adults |
| hs-CRP | A marker of low-grade inflammation | Optional. A high result is a risk-enhancing factor |
ApoB: counting particles
LDL cholesterol tells you how much cholesterol is being carried. ApoB tells you how many particles are carrying it. The two usually agree, but not always, and it is the particles that enter the artery wall.
An expert consensus from the National Lipid Association states that when LDL cholesterol and ApoB disagree, cardiovascular risk generally lines up better with ApoB.2 The 2018 US cholesterol guideline listed an ApoB of 130 mg/dL or higher among its risk-enhancing factors, measured in selected people.3 In other words, guidelines treat it as a useful extra, not a routine test for everyone. See our ApoB test guide.
Lp(a): the inherited one
Lp(a) is a cholesterol-carrying particle whose level is set mostly by your genes. It is common, too. The National Lipid Association estimates that about 1 in 5 people have a high level.4
A standard panel cannot show it. The cholesterol inside Lp(a) is simply counted as part of your LDL cholesterol, so a person with a high Lp(a) can have an ordinary-looking panel. We explain this in Lp(a) vs. LDL cholesterol.
Because the level barely changes through adult life, one measurement is usually enough. Both the National Lipid Association and the 2026 ACC/AHA guideline support measuring Lp(a) at least once in adults.45 Of the three added tests, this is the one with the firmest backing.
hs-CRP: inflammation
hs-CRP measures low levels of C-reactive protein, a marker of inflammation in the body. The 2018 US cholesterol guideline listed an hs-CRP of 2.0 mg/L or higher as a risk-enhancing factor.3
The evidence has limits. The US Preventive Services Task Force concluded in 2018 that the evidence was insufficient to assess the balance of benefits and harms of adding hs-CRP to traditional risk assessment in adults without symptoms.6 The result also swings with infections, injuries and other conditions, so a single high value needs context. Our hs-CRP test guide covers the ranges and what throws them off.
What "advanced" should not mean
More tests are not automatically better. Some commercial panels add a long list of markers with far less evidence behind them than the three above. A result that does not change any decision adds cost and worry without adding protection.
A fair test of any added lab is simple: would a high or low result change what you and your clinician do? For ApoB, Lp(a) and hs-CRP, guidelines give a clear answer for people whose risk is borderline or intermediate. For many other markers they do not.
Who gains the most from the added tests
- People with a parent or sibling who had early heart disease.
- People whose calculated risk is borderline or intermediate, where a risk enhancer can tip a treatment decision.
- People with high triglycerides, prediabetes or diabetes, where LDL cholesterol can understate particle count.
- People whose cholesterol is normal but who still have reasons for concern.
If you are at clearly low risk with no family history, the added tests are less likely to change anything, apart from the one-time Lp(a).
Advanced labs in a Cardio Res-Q assessment
Both Cardio Res-Q assessments include ApoB, Lp(a), hs-CRP, homocysteine, insulin, glucose and A1c, along with the Cleveland Heart cardiac panel. That panel reports Lp(a), ApoB, hs-CRP, oxidized LDL and small dense LDL, plus other proprietary markers. Dr. Varano goes through the full results with you. The Comprehensive Assessment is $775, and the Enhanced Assessment ($999) adds a CIMT ultrasound and a coronary calcium score.
You are asked to fast for 10 to 12 hours before your labs. If you have recent results from your own doctor, ask our team whether to bring them. Read what to expect at your assessment, or go to the Cardio Res-Q program page to book.

Three quick questions about the risk factors we screen for. Your answers stay between you and the clinic.
Frequently asked questions
Will my regular doctor order ApoB, Lp(a) and hs-CRP?
Many will if you ask, and all three are ordinary blood tests that most labs can run. Coverage varies by plan, so check before the blood draw.
If my standard panel is normal, can I skip the rest?
A normal panel is good news, but it cannot show a high Lp(a), and it can miss a high particle count in some people. Current US guidance supports checking Lp(a) once in adulthood whatever the standard panel shows.
How often do advanced labs need repeating?
Lp(a) is generally measured once. ApoB and hs-CRP may be repeated to follow changes over time or on treatment. Your clinician sets the interval.
Is homocysteine an advanced heart lab?
It is included in Cardio Res-Q labs, but the evidence for it is different from that for ApoB or Lp(a). We cover it in a separate guide on homocysteine and heart risk.
